Referring to Figures 1, drawings, there is provided a distribution .casing 1, preferably arranged in the rear part of the board A, of the automobile where the system is installed. Said casing is divided into two compartments 2 and 3 by a partition 4, and has 16.

twelve bores in which are threaded the ends of pipes 5, 6, .7 and 8 communicating with compart-' ment 2; said pipes being provided with cocks 9,

10, 11 and 12. The compartment 3 has connected thereto pipes 13, 14, 15 and 16 ,which are not 20 provided withcocks; in the lower part'of thecasing 1 and in communication with compartment 2 of sameare the pipes 17 and 18, the latterbranched in pipes 19 and 20, of which 19 is connected with compartment 2 and 20 with 25 compartment 3 of the casing 1. Another pipe 21 is connected to compartment ,3.

Pipes 17 and 21 are provided with shut-off valves or cocks 22 and 23, and branches 19 and 20 communicate with pipe18 through a double 7 way cook 25.

As shown in Figure 6 cocks 9, 10, 11, 12, 22, and 23 include a casing 26 longitudinally bond as shown at 27, on the ends of which the corresponding pipes, are threaded. The casing has 5 another bore in which a valve body 28 is fitted, said body having a bore 28' registering with bore 27 when the cock is open. The valve body 28 is securedto the casing 26 through a nut 29, as shown in. Figure 4. The rear end of body 28 is mounted on an axle 30, which in the cocks 9', 10, 11 and 12 is extended to the board A within the reach of the driver by means of handles 31,32, 33, and 34. The cocks 22, 23, and 25 have a crank 35 connected to a rod 37 pivotally mounted to an axle 38 secured outwardly to the casing 1. In the upper end of'the rod 37 a crank 38' is connected by means of a slot and pin connection. The crank 38' is secured to an axle 39 of sumcient length to be operated in the board A through the handle 39'. The double way cook 25, as detailed in Figure '7, is-similar in construction to above referred cocks its casing 40 being of Y shape and the valve body 41 having divergent borings 42 regis- 2, 3 and'4 of the. 10

passage of the fluid used.

The pipe 17 communicates with a fluid tank B, the fluid preferably used being oil, and the tank being arranged in the frame of the vehicle. Pipe 18 communicates with the casing 48 of a pumping device, which as illustrated in Figure 14 is swingingly suspended from a short shaft 44 secured to the'engine block C, or in another suitable place, the suspension being maintained through the bearing 43 in the upper part of the casing 43.

The casing 43 includes three compartments, 45, 46', 4'7, the compartment 45 being the suction chamber, 46 the barrel and 4'7 the compression chamber. The partitions 48 which separate said chambers have valve openings fitted with conical valves 49, 50, and 51 designate the suction and compression pipes of the pump, the pipe 50 communicating with the tank B while the pipe 51 is connected to the pipe 18. Secured to the casing 43 is the cylinder 52 in which the plunger 53 acts, the latter-being provided with the packing 54 and being operated through a mechanism enclosed within the casing 55, comprising aconnecting rod 56 connected to a crank 5'7 connected to the gears 58, 59, 60 and 61, and driven through a pulley 62 mountedon a shaft 63 supported in bearings. said pulley being connected to the driving shaft. of the engine.

As shown in Figure 14 in a suitable place of the engine block there is a pin 62 in which is pivotally connected the angle lever 63 one of the arms which bears a roller 63 which engages with the lower part of the casing 55. The other arm of the lever is connected to a rod 64 of a suitable length to be operated from the board A, and which rod is threaded to a block 65 the upper face 65' of which is toothed. By 65" is designated a recess in the same block 65 wherein is housed a dog 66 pivoted to a horizontal pin 67.

The block 65 has an axial bore through which a stem 68 is mounted: said stem having its inner bevelled end engaging the dog 66, as shown in Figure 16.

One end of the block 65 is reduced in its section and threaded and a knobv 69 is secured thereon. Said knob 69 hasan opening through which fits snugly the head '10 whichis threaded to one end of the stem 68, a spring '71 being coiled thereon.

To the board A is secured a bracket '72 on which is pivoted the pawl '73 connected with the tooth 65' of the block 65 and being engaged also on its lower part with the dog 66.

On the rear and front axles on the vehicle are suitably secured four raising devices, or

jacks, which are designated in the general view 1 as D,.E, F and G. In Figures 23, 24, and 25 is illustrated a preferred way to secure said jacks to the axles, and referringto Figures 23 and 24, '74 designates the front axle of theyehicle, usually of I shape in section, being sided by blocks 75, in order to obtain a square section for same. Rearwards of the cylinder '76 of the corresponding Jack is arranged a U shaped clamp '77 the flanges '77 of which are secured through bolts '79 with an opposite clamp '78. v

In Figure 25 the means to secure the corresponding Jacks to the rear axle is represented;

same consisting of a block 81, of rectangular section fltted-to the axle, thesecuring of same with the iackbeing effected in the same manner as explained above for the front axle.

in the casing 55,, and

.tering with each of the pipes 19 and 20 for the 5, 6, '7, and 8, the pipe 5 in this instance for clearness sake being referred to. The pipe 5 is connected with the upper part of the casing '76. having a check valve 84 which allows the peasage of the fluid from the casing but prevents passage of the fluid into the same. Although said check valve is of well known construction it is detailed in Figures 21 and 22.

The lower part of the casing '76 has a bore where is threaded the end of a pipe 85 which is connected with the corresponding pipes 13, 14,. 15 and 16 of the distributor casing, pipe 13 being referred to for cleamess sake. Said pipe 13 is provided with a check valve 86, identical to the above mentioned valve 84.

Within the cylinder '76 is housed a plunger 8'7, attached to a post 88 the section of which is slightly smaller than the section of the cylinder leaving an annular space 76' between the respective walls for the outflow of the fluid therein.

The post 88 is secured through a threaded stem to a support plate 90. 1

In the lower inner part of the cylinder '76 an abutment '16" is formed in order to provide a frictional fitting with the post 88, havinga packing 91 and packing nut 92 which prevent the leakage of the fluid.

The operation of as follows:

Assuming that one of the rear wheels of the vehicle is intended to be raised, the handle 31 is operated opening the cock 9 of the pipe 5 which communicates with the compartment 2 of the disthis system may be reviewed trlbutor casing 1. The handle 39 is also operated the pump due to the gearing transmission 58, 59,

60, and 61. Therefore, the fluid in the tank Bwill be forced through the pipe 50 to the casing 46 and therefrom to the pipe 51 forward to the pipe 16 where the double way cock 25 is arranged.

The fluid passes through 83, to the upper part the plunger 8'7 downward to the' position illustrated in dotted line in Figur 19. As it was stated before, the check valve 84 will avoid the incoming of the fluid through the pipe 5 to the cylinder '76.

The downward stroke of the plunger 8'7 will end in a level about the level of pipe 13, through which the fluid is returned 3 and therefrom to pipe 23 leading to Once the wheel is raised, and the work required therein ended, the handle 89' is moved in the opposite direction opening the cock 22, closing thecock 23,andclosinginthecock25 them to the-compartment 2' and opening the way to compartment 8. g

the pipe 5 to the pipe of the cylinder '76 pressing The fluid will now flow through the pipe 13 from the compartment 3, and being checked by the valve 86; will be forced to the pipe 85, to. the

annular space 76' acting upwardly on the plunger 87 forcing same upwardsto the position shown in full line, in Figure 19. Upon the continuous operation of the pump the fluid outflows through the pipe to the compartment .2 and returns therefrom through the pipe 17 to the tank B.

When the jack F is raised, the knob IO-is pressed against the spring 71, and the stem 68 pushes the dog 66 raising the pawl 73 and the block 65 will be moved inwardly. This movement will cause'the pushing of the rod 6'4 which stops the action of the lever 63, and therefore the pulley 62 being disconnected stops the operation of the pump. The handles 31 and 39' will be reinstated then in their former position.

If two or more wheels, should be needed tobe raised the operation will-be just the same, it being suflicient to open the cooks corresponding to the operating into two compartments; four fluid operated jacks fixed to the axles. of the vehicle wheels, four pipes in communication with one of the compartments of the distributor and with the upper part of the four fluid operated jacks shut off valves in said pipes; means to operate the opening and closing of the shut-01f valves from theseat of the driver of thevehicle; four pipes in communication with i the other compartment of the distributor and with the lower part of the jacks; two pipes which respectively communicate with one of the com- .partments of the distributor and with the fluid tank; shut-off valves in the last mentioned pipes a branched pipeprovided with -a double way cock communicating each branch of same respectively with each compartment of the distributor, a pumping device with which the branched pipe communicates; means to operate, from the drivers seat, the simultaneous opening and closingof the valves of the three pip s, just mentioned, so as to selectively close one of them and open the other, meanwhile closing the double way cock to .a compartment of the distributor and opening" to the' other; and means to operate the starting of the pumping device from the driver's seat.
